Development of a robotic navigation system for neurosurgery

Area of Science:

• Neurosurgery
• Robotics
• Medical Imaging

Background:

• Image-guided neurosurgery requires precise instrument navigation.
• Robotic systems offer potential for enhanced accuracy and safety in complex brain procedures.
• Current systems face challenges in real-time tracking and instrument guidance.

Purpose of the Study:

• To develop and evaluate a robotic navigation system for image-guided neurosurgery.
• To assess the system's accuracy in guiding surgical instruments for procedures like brain tumor biopsy and Parkinson's disease treatment.
• To integrate real-time anatomical display, magnetic tracking, and robotic manipulation for improved surgical outcomes.

Main Methods:

• The system integrates a computer for real-time brain anatomy display.
• A magnetic tracking device measures instrument positions and orientations.
• A robot manipulator guides instruments to pre-planned trajectories.
• Registration between tracking, imaging, and robotic systems is achieved via external marker coordination mapping.

Main Results:

• The robotic navigation system demonstrated successful guidance of surgical instruments.
• Experimental validation using a skull model for simulated brain tumor biopsy showed high performance.
• The system achieved a positioning accuracy of approximately 2 mm.

Conclusions:

• The developed robotic navigation system is effective for image-guided neurosurgery.
• The system's accuracy supports its application in delicate procedures such as brain tumor biopsies and Parkinson's disease interventions.
• Integration of advanced technologies enables precise and automated instrument guidance in neurosurgical interventions.
